What Low Temperatures Can an Average Car Withstand?

[LeLyla]

An average car can withstand temperatures as low as minus forty degrees Celsius. In the northern regions of China, winter climates are extremely cold, typically ranging from minus 5 degrees Celsius to minus 25 degrees Celsius, with the coldest periods seeing temperatures drop below minus forty degrees. Low temperatures can severely impact a car's operation, particularly during cold starts, leading to noticeable difficulties in ignition, severe wear on assemblies, increased fuel consumption rates, and exacerbated exhaust pollution. When temperatures fall below minus 18 degrees Celsius to minus 20 degrees Celsius, cold starts become quite challenging. If temperatures drop below minus forty degrees Celsius, a car cannot start at all without preheating. During use, a car's engine performance in low-temperature starts is mainly influenced by the viscosity of the lubricating oil, the vaporization properties of the fuel, and the working capacity of the battery. To mitigate the effects of low temperatures on car performance, it is necessary to warm up the car before use. However, the warming-up process does not require the car to remain stationary for an extended period. Instead, after starting the vehicle, allow the engine to run at a high idle speed automatically, and once the idle speed slightly decreases, the car can begin moving.
